Title: Improvements in dampening mechanisms for planographic or lithographic presses
IPC: B41F7/26
Filed: 1922-03-02
Abstract: 192,947. Anglo-American Inventions Syndicate, Ltd., (Harris Automatic Press Co.). March 2, 1922. Damping-apparatus for lithographic and like printing-machines is constructed so that the fountain roller is rotated by change-speed gear so as to vary the amount of water supplied, and the roller is rotated intermittently to an extent which can be adjusted. Means for obtaining an even distribution of the water are described. As shown, a plate cylinder 21 is clamped by a roller 20 receiving its water from a roller 19 which is supplied by a messenger roller 17 which is carried on an oscillating lever 22 which moves roller 17 to and from the fountain roller 13. The lever 22 is oscillated by an adjustable spiral cam 24 on a shaft 25 which is driven from the cylinder 21 by change-speed gearing comprising gear wheels 28, 29 geared by separate trains of geans to a gear cylinder 21. To bring the high-speed gear 29, Fig. 5, into gear, a latch 35 pivoted to a rod 26 splined to the shaft 25 is caused to engage a key-way 37 cut in the gear 29, the rod 26 being operable by a sliding rod to cause the latch 35 to engage either of the gears or to be held in a neutral position against a collar 30 which separates the gears 28, 29. The shaft 12 of the roller 13 is rotated intermittently from the shaft 25, by causing a crank-pin 60, Fig. 8, to oscillate a lever 59 fitted with a pawl 65 which operates a ratchet 66 integral with a gear 68 geared to a wheel 69 on shaft 12. An adjustable guard 70 controls the extent of movement of ratchet 66 for each rocking of lever 59. The pawl 65 may be tripped by a hand-operated curved arm 77, Fig. 1, to free the shaft 12 and allow it to be rotated by a hand-wheel 69a. The water applied by roller 20 is evenly distributed by a second roller 20<b> which may be used alone or in combination with a roller 20<a> which also contacts with the roller 20.

Filed: 1924-03-13
Abstract: 229,507. Brooks, R., and Metropolitan- Vickers Electrical Co., Ltd. March 13, 1924. Controllers with combination of resistances; master control systems.- The resistance in an electric circuit is varied by a large number of steps with comparatively few switches. Tapped resistance sections 3 - - 6 are successively shorted by switches 7 - - 10 so as to decrease the effective resistance between points 1, 2. Switches 7 - - 10 are now opened and simultaneously switches 11, 13 are closed so as to shunt sections 3 - - 6 with an auxiliary resistance 12 and to short a section 14. Section 14 is of such a value that this operation produces a further decrease in the resistance between the points 1, 2. Switches 7 - - 10 are again closed successively and the operation repeated with another auxiliary resistance 16 by the aid of switches 15, 17. This variable resistance can be applied to excitation regulation of motors and generators and to motor starting rheostats, and is particularly applicable to master control systems. The Specification describes the application of this variable resistance to the control of motor excitation, the various switches being contactors energized according to the position of a drum controller.

Abstract: 338,088. Linotype & Machinery, Ltd., (Assignees of Mergenthaler Setzmaschinen- Fabrik Ges.). March 8, 1929, [Convention date]. Trimming type-bars.-In order that type-bars may be trimmed to a uniform thickness along their length, one of the trimming-knives is formed with a resilient cutting edge, and means are provided for deflecting it into a curved form. The knives are thereby set a little farther apart at the centre than at the ends, so as to compensate for the fact that the metal of the typebar is hotter at the centre, which therefore contracts more during cooling. The knife may be divided by a slot c, or a groove, into two sections a, b, which can be drawn together by a screw e, the head of the screw being located in a recess in the upper section b. In a modification, the knife is in two parts spaced apart by three projections, of which the centre one is slightly shallower than the outer ones. Both of the knives may be so formed.

Filed: 1952-03-17
Abstract: Yarns, fabrics and other materials made of interpolymers of acrylonitrile and vinyl-substituted tertiary heterocyclic amines are dyed in an aqueous medium containing an acid dye and 1-10 per cent by weight of nitric acid, based on the weight of the interpolymer.  The process is applicable to interpolymers derived from the vinyl-substituted tertiary heterocyclic amines listed in Specification 693,864 and also alkyl-vinylpyrazines and 2 : 4-dimethyl-1-vinylimidazole.  A third component may be present, e.g. vinyl acetate, vinyl chloride, methacrylonitrile, acrylates p  or methacrylates.  The material may also be a blend of a polymer as above with a polyacrylonitrile which is not receptive to acid dyes. The materials so dyed may be in the form of continuous filaments, staple fibres, yarns, films, rods, tubes or fabrics. Preferred polymers are those blended from polyacrylonitrile and 2-50 per cent of a copolymer of 10-70 per cent of acrylonitrile and 30-90 per cent of vinyl-substituted amine as above; such polymer should contain at least 80 per cent of acrylonitrile. Typical of these are polymers containing 80-98 per cent of acrylonitrile and 2-20 per cent of a vinylpyridine or 80 per cent or more of acrylonitrile and 2 per cent or more of a 1-vinylimidazole.  In the examples, (1) a fabric woven from filament yarn of polyacrylonitrile containing 6 per cent of 2-vinylpyridine is dyed with Crocein Scarlet M00 in a bath containing nitric acid (6.4 per cent of yarn weight); (2) a skein of yarn as in (1) is dyed with Xylene Light Yellow 2G in a bath to which a total of 10 per cent of nitric acid (on yarn weight) is added in four portions; (3) fibres as in (1) are entered into a bath containing Superchrome Yellow RN, Omega Chrome Brown EB, Omega Chrome Black Blue G, Omega Chrome Red B, Omega Chrome Blue 2BL and an ethylene oxide-amine condensate; 10 per cent of nitric acid is added in five portions and after-chroming is carried out with potassium dichromate and nitric acid; the shade is red before chroming, changed to olive drab.
